HENRY F. LARAVA, OF WORCESTER, MASSACHUSETTS.

BELT-FASTENER FOR CONNECTING ENDS OF DRIVE-BELTS.

SPECIFICATION forming part of Letters Patent No. 699,538, dated May 6,1902.

Application filed September 3, 1901. Serial No. 74,136- (No modelh T0aZZ whom it may concern:

Be itknown that I,HENRY F. LARAVA,a citizen of the United States,residing at Worcester, in the county of l/Vorcester and State ofMassachusetts,have invented certain new and useful Improvements inBelt-Fasteners for Connecting the Ends of Drive-Belts; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to belt-fasteners used in connecting the ends ofdrive-belts.

The object of the invention is to providea belt-fastener which shall besimple of construction, durable in use, and comparatively inexpensive ofproduction and which may be easily and quickly connected to the abuttingends of the belt.

With this and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,which will be hereinafter more fully described, and particularly pointedout in the,

appended claim.

In the accompanying drawings, Figure 1 is a perspective view of themeeting ends of a belt, showing them connected together by my improvedfastener. Fig. 2 is a longitudinal vertical sectional view through thebelt and fastener. Fig. 3 is a detail perspective view of the partsforming the fastener, and Fig. 4 is a plan view of the blank from whichone part of the fastener is shaped.

Referring to the drawings, A and Bdenote the meeting ends of a belt, and0 denotes the improved belt'fastener connecting the ends of the belttogether. Each fastener is composed of a flat plate or strip D, made,preferably, of spring metal and provided at each end with an eye E and aplate F, preferably of spring metal, having at each endtubular rivets G,which project at an angle to the body of the plate and are adapted to beinserted through holes punched through the ends of the belt and throughthe holes in the platel) and then mashed or flattened. The tubularrivets are integral with the plate F and form extensions of the same andare made from'a blank, as shown in Fig. 4, the extensions thereof beingprovided with slits H, and by bending the edges of the side portions itnearly together in tubular or circular shape and then bending the sameat h vertically upward the lower edges of the thus formed rivets willfold over and rest on the ends of the body portion of the plate F, asshown in Fig. 3, the slits and approximating edges of the side portionsof the rivets rendering the same to be more readily spread apart by theinsertion of a blunt tool in the hollow of the rivets. After being thusspread the ends are hammered fiat, as shown in Fig. 2, thus securelyconnecting the ends of the belt together.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, andadvantages of my invention will be readily understood Without requiringa more extended explanation.

Various changes in the form, proportion, and details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-- A belt-fastener for connecting the ends ofdrive-belts comprising a plate having slitted integral extended endsadapted to be bent to form tubular rivets on the V upper terminal endsof said plate, the upward-extendingends when bent forming slits oppositethe slits in the integral extended ends, and a plate with eyes coactingwith said rivets, substantially as specified.

In testimony whereof I have hereunto set my hand in presence of twosubscribing" wit Witnesses:
